| Open AccessProtection against overfeeding-induced weight gain is preserved in obesity but does not require FGF21 or MC4R
Overfeeding triggers a mechanistically ill-defined compensatory response that counteracts weight gain. Here, the authors show that the defence against overfeeding is preserved in obesity, and that it is independent from FGF21 and MC4R.

| Open AccessRegulating protein corona on nanovesicles by glycosylated polyhydroxy polymer modification for efficient drug delivery
The dynamic protein corona hinders the uptake of nanocarriers in desired target cell populations, limiting their bench-to-bedside translation. Here the authors reveal that the modification of hydroxyl and amino functional groups on nanovesicles can rationally regulate the composition of protein coronas to improve the efficiency of targeted drug delivery.

Gain-of-function mutations in NLRP3 result in Cryopyrin-Associated Periodic Syndrome in human patients. Here authors show that although these NLRP3 variants are constitutively active, they preserve their responsiveness to external pro-inflammatory stimuli, and they interfere with the immune-metabolic inflammatory pathways in monocytes.
